## What it is
A query batching executor for the Ruby graphql gem that lets GraphQL resolvers batch database lookups via custom loader classes. Loaders return promises and group loads by arguments, eliminating N+1 query problems in GraphQL APIs.

## Use cases
- batch database queries in graphql-ruby resolvers
- avoid N+1 queries in GraphQL API
- load records by id in batched fashion
- batch load associations for active record models
- chain dependent queries with promises in resolvers
- clear cached loaders after mutations

## When to choose
- you use the graphql gem and face N+1 query issues
- you want promise-based batching similar to Facebook's DataLoader in Ruby
- your resolvers load records or associations repeatedly per query

## When to avoid
- you don't use Ruby or the graphql gem
- you use graphql-ruby's built-in GraphQL::Dataloader instead
- your schema has no repeated per-object data lookups

## Facets
- artifact type: library
- maturity: stable
- function: graphql, middleware, caching, database
- domain: web-development, backend, apis, databases, developer-tools
- platform: ruby
- tags: graphql-ruby, query-batching, n-plus-one, dataloader, promise-based, active-record
